Overview / Usage

I am working on an app which will be individual for any college or comapny where it contains all the details about that college or company like their official website.But the difference here will be that all the members of the same company or college can join or contact to each other through this app.They can post different stories and any important notifications.The only restrictions will be here is that any person which is not a member of that organisation they can't connect to these peoples.this can be maintained at the time of registration they need to upload their organisation id card.
